It is the purpose of this glossary to aid the general public in better understanding NWS products. Previously, this book was only availableonline as a search tool. This hardcopy edition is based on material posted to the website as of late 2012. We believe this edition is more useful in many situations.< Less

This document is the sixth in a series of Geotechnical Engineering Circulars (GEC) developed by the Federal Highway Administration (FHWA). This Circular focuses on the design, procurement and...

The intended users are practicing geotechnical, foundation and structural engineers involved with the design and construction of transportation facilities.< Less

In the 1930s the Works Project Administration, sponsored by the United States, set out to document the lives of former slaves to find out what life really was like.
What you are about to hear is the... More > actual words of men and women who lived under slavery and what life was truly like.
Some of the words you may hear may be disturbing and painful to some. It stands as a reminder the horrors and terror of slavery in the United States.

This book is the Federal Highway Administration’s primary reference of recommended design and procurement procedures for shallow foundations. It presents state-of-the-practice guidance on the... More > design of shallow foundation support of highway bridges. The information is intended to be practical in nature, and to especially encourage the cost-effective use of shallow foundations bearing on structural fills. To the greatest extent possible, the document coalesces the research, development and application of shallow foundation support for transportation structures over the last several decades. Detailed design examples are provided for shallow foundations in several bridge support applications according to both Service Load Design and Load and Resistance Factor Design methodologies. Guidance is also provided for shallow foundation applications for minor structures and buildings associated with transportation projects.< Less

This manual is the reference text used for the FHWA NHI courses No. 132042 and 132043
on Mechanically Stabilized Earth Walls and Reinforced Soil Slopes and reflects current practice for the design,... More > construction and monitoring of these structures. This manual was prepared to enable the engineer to identify and evaluate potential applications of MSE walls and RSS as an alternative to other construction methods and as a means to solve construction problems. The scope is sufficiently broad to be of value for specifications specialists, construction and contracting personnel responsible for construction inspection, development of material specifications and contracting methods. With the aid of this text, the engineer should be able to properly select, design, specify, monitor and contract for the construction of MSE walls and RSS embankments.< Less

The use of micropiles has grown significantly since their conception in the 1950s, and in particular since the mid-1980s. Micropiles have been used mainly as elements for foundation support to resist... More > static and seismic loading conditions and less frequently as in-situ reinforcements for slope and excavation stability. Many of these applications are suitable for transportation structures. Implementation of micropile technology on U.S. transportation projects has been hindered by lack of practical design and construction guidelines. This manual is intended as a "practitioner-oriented" document containing sufficient information on micropile design, construction specifications, inspection and testing procedures, cost data, and contracting methods to facilitate and speed the implementation and cost effective use of micropiles on United States transportation projects.< Less

This manual is intended to provide a technical resource for engineers responsible for the selection and design of drilled shaft foundations for transportation structures. This manual embraces both... More > construction and design of drilled shafts, and addresses the following topics: applications of drilled shafts for transportation structure foundations; general requirements for subsurface investigations; construction means and methods; LRFD principles and overall design process; geotechnical design of drilled shafts for axial and lateral loading; extreme events including scour and earthquake; LRFD structure design; field loading tests; construction specifications; inspection and records; non-destructive integrity tests; remediation of deficient shafts; and cost estimation. This volume includes Chapters 16-23 and the appendices.< Less
